Particular Application Bandwidth Utilization on Cisco Router

[Sureshkumar B]

Hi team, Currently one of my critical payment application is running through internet and due to bandwidth congestion some of transactions are declining.

So we decided to procure a Point to Point leased line to that merchant. And we don't know how much bandwidth is required for that application and we know the peak bandwidth utilization timings is between morning 8.00 to 8.05 AM only. So is there any mechanism or commands to calculate the bandwidth utilization on Cisco router of that particular application on this window.

How to know what is bandwidth required for that application on our internet cisco router. (Like IP accounting, IP flow)

The problem with stats from IP accounting or netflow, they indicate how much bandwidth was used, but your question was knowing how much bandwidth is needed.

Well, on some platforms and IOS versions, Cisco implemented QoS Bandwidth Estimation using Corvil Technology, see http://www.cisco.com/c/en/us/td/docs/ios/qos/configuration/guide/convert/qos_bndwth/qos_bndwidth_est.html for more information.

If your platform supports this technology, you would also need to SNMP poll the estimator's stats, during the time period of interest.
